This “export filter” plugin for Lightroom allows you to apply a device-specific crop to an image during output, so that images fully fill the screen when viewed on the device.
I use it to prepare images for my iPad and iPhone, but it can be used with any device in mind such as digital picture frames, tablet computers, TVs, smartphones, etc.
This plugin works in Lightroom 5, Lightroom 4 and Lightroom 3 (though some features may be missing in older versions of Lightroom).
The same download works for both Windows and Mac. See the box to the upper right for the download link (in orange) and installation instructions.
How To Use
For explicit details on how to use the plugin, see my companion post:
Independent JPEG Group Software
This plugin software is based in part on the work of the Independent JPEG Group. The crop, if performed, is lossless (it does not lower the quality of the image) because it uses the Independent JPEG Group's most-excellent jpegtran software to do the crop.
This plugin is distributed as “donationware”. I have chosen to make it available for free — everyone can use it forever, without cost of any kind — but unless registered, its functionality is somewhat reduced after six weeks.
Registration is done via PayPal, and if you choose to register, it costs the minimum 1-cent PayPal fee; any amount you'd like to add beyond PayPal's sliding fees as a gift to me is completely optional, and completely appreciated.
Note: a Lightroom major upgrade, such as from Lr4 to Lr5, de-registers the plugin in the upgraded version, so if you want to maintain registration, a new ($0.01 if you like) registration code is needed in the upgraded version. It makes for a hassle every couple of years, I know. Sorry. See this note for details.

Upgraded to the embedded copy of ExifTool to version 9.46.
|20131102.29||Update for OS X Mavricks|
Added a bunch of stuff to the device database, including new Apple iPads announced today.
Fixed a bug with the aspect-ratio reporting in the keyword-set dialog.
Now works with keywords even if they're not at the root of your keyword tree, so you can freely move the keywords to one subgroup (e.g. "Crops") and things still work smoothly. This creates some ambiguity if you have the same keyword in multiple locations, so don't do that.

Tweak for Lr4.1RC2.
The crop-preview tool (OSX only) color selection stuff had stopped working... fixed it, and gave that whole area some extra UI love.
Some keyword interaction in the crop-preview tool wasn't working in all cases.
Enhanced the send-log dialog to hopefully make reports more meaningful to me, yielding, I hope, the ability to respond more sensibly to more reports.
